I made it...cut and folded a piece of fleece, sewed a couple of stitches and added a band...it's a real fashion statement, isn't it? It looks like a pigs snout but it works really well and the price was right...LOL...

Anyone interested in vapor barrier clothing might want to have a look at Stephenson's Warmlite website. They have been making vapor barrier clothing since the late 1960s. Their laminated fabric, however, is not ultralight.

The Stephenson's Warmlite VB Fuzzy Stuff Clothing is not overly heavy. My L VB top weighs 5.4 oz and my M VB Bottom (no zipper) only weighs 4.4 oz. In a sleeping system, these may well add about an additional 10 degrees F to the low temperature range. Additionally, if using down for your clothing and sleeping bag loft (if your clothing is dry), you should not have much issue with vapor entering the fill material and lessening loft.

What Skurka has accomplished is very impressive. We can learn a lot from his trip and the second time around maybe do it better? I have posed some questions and raised some issues with my FORTY BELOW thread on the winter hiking forum. That was the temperature that Skurka missed by about two weeks.
